Title: Materials Data on Eu2Ti2O5 by Materials Project

Abstract

Eu2Ti2O5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are two inequivalent Eu2+ sites. In the first Eu2+ site, Eu2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Eu–O bond lengths are 2.59 Å. In the second Eu2+ site, Eu2+ is bonded to twelve O2- atoms to form EuO12 cuboctahedra that share corners with four equivalent EuO12 cuboctahedra, faces with four equivalent EuO12 cuboctahedra, and faces with eight equivalent TiO5 square pyramids. There are four shorter (2.80 Å) and eight longer (2.86 Å) Eu–O bond lengths. Ti3+ is bonded to five O2- atoms to form TiO5 square pyramids that share corners with five equivalent TiO5 square pyramids and faces with four equivalent EuO12 cuboctahedra. There is one shorter (1.97 Å) and four longer (1.98 Å) Ti–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four Eu2+ and two equivalent Ti3+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent Eu2+ and two equivalent Ti3+ atoms.
